To alt whom it 771/011] GORCBWZ.

Be it known that l, WILLIAM E. HENRY, s citizen oi the United States,residing at New Britsin, Hartford county, Connecticut, have inventedcertain new and useful improve ments in Door Closers and Checks, ofwhich the following is 2. full, clear, and exact description.

lily invention relstes to improvements in door closers end checks.

l.l1e object of the invention is to provide e door-closer which can beeasily menuiectured, quickly sembled, adjusted, and epplied to either aright hend or e left-hand door at will, the scene operating with equaleilectiveness irrespective of the swing of said door.

Broadly, the invention relates to improve ments in the closer mechanismirrespective I of the checking mechenism employed and hether seidchecking mechanism he pert of independent of the closer. Neverthelessrecombination with certain checking mechanism hereinafter more iullydescribed it has merry sdventeges.

is the drawings, Figure l is e plan view of the door-clcserwith checkabsent. .Fi .2 is a. v tical sectional view on theplene of t is line Z,Fig. 1. end shcwisg'the check attached.

s V rverticel sectional view of the closer and che 5. taken on e plcneetright angles to the section. of Big. 2. Fig. l is e horizontalcross-section of the deer-closer. Fig. 5 is a view of the rear side ofthe closer, the check being broken sway.

in the drawings 1 heve shown the closer in combinetion with the check,since some of the claims cf my invention are predicated on thiscombination. The lorosd claims, however, ere based upon the door-closer,and the same will therefore he described in detail. The GhQClKlXEapparatus need not be described as iu ly es'would otherwise benecesssry, because in a separate application, Serial No. 259,081,1iledMay 6, 1905, I claim the same as an independent invention.

3. designates the heckinggeplete, such as ordinarily used, and by whic 1[rllGGlOSBI may be secured to a door in the well-known In sneer.

designates the closer ccse, within which the sprmgehsmber.

0 designates e spindle.

4 desigiistes a lever detschebly secured on the spindle 3.

The means for connecting this door-closer with the door-cesing is thatwhich is customcry end well known end need not, therefore, be describedherein.

4 designates an extension from the levererm 1 is same performing thevaluable function hereinafter set forth.

The spindle 3 is provided with e, suitable hearing or bearings within oron the cese 2.

5 designates a cap or cover-plate adapted to the case 2, ssid cep havings'depending ortiorrfi arranged to pro'ect downwardly nto the case 2 andpr'efe'rehly of. cylindrical orm.

5 designates an outer flange on the cap 5, which overstcnds the up eredge of the case 2 end preferably neatly hts the sense.

6 designates e sleeve surrounding the s pindle 3 end tithing a. suitablebearing thereon.'

The upper end of this sleeve is extended leterelly to form the ratchet 6ratchet 6 is :1 depending flange or bearing 6 for e .memher 7, whichcooperetes with the ratchet 6* when it is desired to very the splintension. This member 7 carries e suitelgle locking device-7, whereby thesame may be interlocked with the ratchet 6. in the form shown thislocking device 7 is spewl carried by member 7.

7 designates an extending lug upon the member 7.

The

1 designates e stop on the back 1.

lug 7' is so arranges as to normally beer against one side of thisstop 1. The cap 5 carries a lug 5, which is so arrai iged as to normallybear against the opposite side of the stop 1 This is seenin Figs. 1 aged5.

The orojection l upon the lever s is substantially that of a hook in theperli culer form shown and projects downwardly, so as to stand betweenthe upper part of the lug 7 on member 7 and the upper pert of lug 5 onthe cap 5. The art 4 swings clear of the stop 1 and will w 1en swun moveeither the member 7 or cap 5 throng 1 its engagement with the aforesaidrespective lugs.

8 designates a. spring arranged around'the spindle 3 and Within thespring-chamber.

"Oilseed 8 of this sprin r engages in 9. slot or "recess in the well 5*oi the cap. is best Below this are seen in File. 3 and 4. The other end8* of the spring'engages with a slot or recess in the sleeve 6. f Thisis best seen in Figs. 2 and 4;.

To put the sprin under tension, theratchet 6 will be rotate in thedirection of the arrow, thereby'rotating the sleeve 6\ When the springhas been ut under the desired side of said stop.

The operation will now be apparent. Whenthe lever e is rotated in.either direction, it Will encounter the opposition of the spring. Forexample, when said lever is moved in one direction the lever extension 4will engage the 111 7 and rotate the sleeve 6,, (the lug 5 being eld byetc 1,) increasing the tension in the spring. hen the lever disreleased, the spring will re turn to its normal position. (Shown in thedrawings.) If the lever 4 is moved in an opposite direction, theextension 4 will engage the lug 5 and will rotate the exp 5 anddepending wall 5' which in turn v I carry around "with it the outer endof the spring, increasing the tension therein. During this movement theh1g7 will be held by the stop 1. When pressure is released, the lever awill, as before, he returned to its normal position. 9 designates a bandwhich surrounds the spring 8, sons to keep it from unwindingwhenremoved. This-band larformsno function when the parts are allassembled ready for use. It does, however, facilitate the insertion. andremoval of the sprin when'the assembled. or ta en down, spr1ng-reta1nersare Wellf check is being lhese hand lnre known, and I lay no claimthereto herein.

When the closer is used in combination with a check in-which thechecking-cylinder is formed with or connected directly to the sprin-oase 2, the construction is referabl as to lows: 10 designates a cyliner withi which. is located one or more istons. If this cylinder isarranged to contain li uid, a suitable iartition 11 is arranged to c oseoil the liqui -chamher from the spring-chamber. n the particular formshown in the drawings two pistons 12 12 are provided, and said pistonswork diametrically o positel At the lower end of the spindle 3 t ore isa double crank, indic'atcd at 13 14.)

the medium of a connecting-rod 13, whilet e crank 14- is connected tothe other piston through tie medium of the connecting-rod 1 3, Thesecranks are arranged out of line, so that the connecting-rods will notinterfere in crossing the center. This is very advantageous incombination with my improved door-closer, because, as is clear from thelore going description, both the closer and the The crank 13 isconnected with one of the pistons 12 throu 'h semis check may be usedwithout change on either a right or a left hand door. In the drawingsthe pistons are shown in ap roximately the position in which they stanwhen the door 18 closed. When the door is opened, no matter which waythe levenarrn 4 turns the pistons will be moved apart and toward theends oi the cylinder 10, the liquid flowing freely past thecheclcvalvc's 15 15 in said pistons and into the space between saidpistons. When the door closes, the direction of rotation of the s indle3 is reversed, and the pistons 12 are rawn toward each other,thecheck-valves 15 15 closing, whereupon the liquid to reach the otherside of the pistons must pass through the vagina-controlled passage(indicated at 16, .Fig. 3.

To take down the door-closer, it is merely necessary to release thelocking device 7*, whereupon the sleeve 6 will turn until the tension ofthe spring is relieved therefrom. When this occurs, the spring will beembraced tightly by the band 9. Upon removing the lever 4 from the upperend of the spindle the sleeve 6, the cap 5, and spring 8 may be quicklyand easily withdrawn with very little effort. To assembl these steps arereversed.

The simplicity of operation, the facility with which the various partsma be removed or assembled or adjusted, an the fact that the closer canbe applled to eitherarighthand or a left-hand door Withoutchan e in thearrangement of any of the arts all furr nish substantial benefits and a.vantages.

What I claim is-- 1. In a door-closer, a spindle, a lever-arm rigidlysecured thereon and having a rearward extension, a spring surroundingthespindle, a stop at the rear oi the closer-case and externallythereof, and adjustable COD." nesting means engaged by the ends of thespring and arranged to engage said lever-arm extension and said step,whereby the former is normally held under spring restraint in .a

definite position relatively to said stop.
